Guide :Grilling : VGBQ300T (NG) All-in-One Grill / Smoker
Flame is too small, does not get hot enough.
This grill is in a salt water environment - ocean less than 100 ft away.
The left knob to increase the heat has become very hard to turn. Coincidentally, when this happened, the flames will not go very high, on either side. We know there is fuel, but there is not enough heat to cook food.
